Climb Curves - Turbojet. -- why? Raymer, Daniel P. (1992). The goal of maximum wing loading may not be as obvious to the novice designer but this means the wing area is kept to a minimum which gives lower drag. 2.5 Bernoulli's equation for subsonic flow states that: If the velocity of an airstream within a tube is increased, the static pressure of the air decreases. 2.19 Standard temperature for degrees C is ___________. The method normally used is called constraint analysis. But, in a jet, you'll often fly close to your best range speed. The relationship above, since it does not depend on the thrust, will plot on our constraint analysis chart as a vertical line in much the same way the stall case did, but it will be just to the left of the stall line. From the spreadsheet, this climb angle can be read. Find the potential energy. Rate of Climb formula. 11.23 If an aircraft traveling down a runway has a tire pressure of 200 psi and no other information is available, the approximate speed to which total dynamic hydroplaning may occur is __________. Constraint analysis is essentially a way to look at aircraft weight, wing area, and engine thrust for various phases of flight and come to a decision about meaningful starting values of all three parameters for a given set of design objectives. 4.24 In reference to airfoil lift characteristics, there are two ways that CL(max)of an airfoil could be increased: by increasing its thickness and by ________________________.

The optimum will be found at the intersections of these curves. 9.1 The power-required curves for an increase in altitude show that the, Pr increases by the same amount as the velocity, 9.2 A propeller aircraft in the dirty condition shows that the Pr moves up and to the left over the clean configuration. 37 0 obj By optimum we mean that we are looking for the minimum thrust-to-weight ratio that will enable the airplane to meet its performance goals and we would like to have the highest possible wing loading. We might find, for example, that by accepting an additional 500 feet in our takeoff ground run we can get by with a significantly smaller engine. 4.21 When analyzing the air moving from the leading edge toward the trailing edge of a wing, until the air reaches the point of minimum pressure it is in a favorable pressure gradient. It says that we need a higher thrust-to-weight ratio to climb than to fly straight and level. False Propeller aircraft are more efficient than jet aircraft because: They process more air and don't accelerate it as much Turboprop aircraft are classified as power producers because: Both A and C: This process would become even more cumbersome as we added other design objectives such as a minimum turning radius or a minimum stall speed. Multi-engine propeller (engines on the wings). A head wind is encountered. 8.6 Propeller aircraft are more efficient than jet aircraft because, They process more air and don't accelerate it as much, 8.7 Turboprop aircraft are classified as power producers because. Hg and a runway temperature of 20C. 13.1 The G's required for an aircraft to maintain altitude in a coordinated turn are determined by the bank angle alone. We could get a different curve for different cruise speeds and altitudes but at any given combination of these this will tell us all the combinations of thrust-to-weight values and wing loadings that will allow straight and level flight at that altitude and speed. Adapted from Raymer, Daniel P. (1992). 9.11 As a power-producing aircraft burns off fuel, airspeed should be ____________ to maintain maximum range. Obviously altitude is a factor in plotting these curves. What other design objectives can be added to the constraint analysis plot to further define our design space? Adapted from James F. Marchman (2004). 10.16 As a rule of thumb, a 5% increase in takeoff distance can be expected for every _______ of uphill slope. Either can be used depending on the performance parameter which is most important to meeting the design specifications. The pilot selects the desired RPM with a leaver, and a control governor automatically changes the blade pitch to maintain a constant RPM. Fortunately, the answer is yes. 10.5 What effect does a tailwind have on takeoff performance? The analysis may suggest that some of the constraints (i.e., the performance targets) need to be relaxed. Maximum rate of climb for a propeller airplane occurs: a. at L/D max b. at CLmax c. at PRmin d. at (PA-PR) max. 12.21 When taking off in a microburst, a pilot should be aware of what change in performance when going from a headwind to a tailwind? A car can be designed to go really fast or to get really good gas mileage, but probably not both. 10.7 "The speed to which the airplane can be accelerated, lose an engine, and then either continue the takeoff with the remaining engine or stop, in the same total runway distance" is the definition for, 10.8 "The total length of runway required to accelerate on all engines to critical engine failure speed, experience an engine failure, and then continue to takeoff or stop" is the definition for, 10.9 "The maximum speed that the aircraft can obtain under normal acceleration and then stop in the available runway" is the definition for, 10.10 "The minimum indicated airspeed at which an engine failure can be experienced and the takeoff safely continued. Don't let the length of this answer fool you, it is actually the fastest path to a solution, starting from what we're given to work with in the original question. The formula is ROC in FPM = ExcessHP*33,000*Propeller efficiency divided by All up Mass in LBS. 11.17 Headwinds and tailwinds affect the landing distance by the same amount as they affect the takeoff distance. where , for example, and .The power available is a function of the propulsion system, the flight velocity, altitude, etc. 5.21 Wingtip vortices are formed by higher-pressure air beneath a wing moving into __________ pressure air above the wing. c. By how many fringes will this water layer shift the interference pattern? Copyright 2023 CFI Notebook, All rights reserved. Figure 6.1: Finding Velocity for Maximum Range Calculate (or find in Table 2.1) the approximate Density Altitude. Note that with a curve shaped like the one you've included in the question, the precision of your final answer is not going to be extremely sensitive to how well you are able to determine the exact point where the line from the origin is tangent to the graph. 13.8 (Reference Figure 5.4) An aircraft flying at 200 knots can pull how many G's before stalling the aircraft? This can be put into the drag equation with the numbers found above to get the thrust or power needed to reach that maximum speed. The takeoff equation seen in an earlier chapter is somewhat complex because takeoff ground distances depend on many things, from drag coefficients to ground friction. Figure 9.7: Kindred Grey (2021). 11.12 Which of the following aircraft derive more lift due to high power settings? 5.6 Which of the following is a type of parasite drag? How can I get the velocity-power curve for a particular aircraft? Here we should note that the space to the right of the dashed line for stall is out of bounds since to fly here would require a higher maximum lift coefficient. 2.6 The corrections that must be made to indicated airspeed (IAS) to obtain calibrated airspeed (CAS) are: 2.7 The correction from equivalent airspeed (EAS) to true airspeed (TAS) is dependent on: 2.8 An airplane is operating from an airfield that has a barometric pressure of 28.86 in. MathJax reference. 9.8 For power-producing aircraft, to maximize both efficiency and performance, you must (best answer). Note also that the units of the graph need not be the same on each axis for this method to work. Normally we would look at turns at sea level conditions and at takeoff weight. Or in some cases the power-to-weight ratio (P/W) is used instead of T/W. The solution can then be directly read from the graph. 11.3 How does a weight increase affect landing performance? TK. How many "extra" wavelengths does the light now travel in this arm? 2.21 Calibrated airspeed is __________________ corrected for position and installation errors. This can then be used to find the associated speed of flight for maximum rate of climb. For a propeller-powered airplane, at an airspeed just above stall speed and below L/D MAX. 13.16 (Reference Figure 14.10) What airspeed should you fly if you wish to fly a standard rate turn using 30 degrees of bank? Each plot of the specific power equation that we add to this gives us a better definition of our design space. 10.17 Which of the following is the speed at which an aircraft must be accelerated at or before reaching 35 ft at the end of the runway? Available from https://archive.org/details/9.4_20210805. What is the wavelength of this light as it travels through water (nwater=1.33)\left(n_{\text {water }}=1.33\right)(nwater=1.33) ? 1.8 An aircraft is traveling west at an airspeed of 120 knots and is experiencing a crosswind of 20 knots from the north (90). 12.15 Which wing planform is considered to be the most aerodynamically efficient? Calculate (or find in Table 2.1) the Pressure Ratio: 2.9 An airplane is operating from an airfield that has a barometric pressure of 28.86 in. Under what conditions can the maximum angle of climb be achieved for jet and propeller aircraft? Best angle of climb (BAOC) airspeed for an airplane is the speed at which the maximum excess thrust is available. endobj The number of distinct words in a sentence. Absolute Ceiling- This is the maximum density altitude that the airplane is capable of attaining or maintaining at max gross weight in the clean configuration and max continuous power. 11.11 In most cases, an aircraft that has a high rate of descent on final approach should ____________. 3.25 The rudder controls movement around the ________________ axis. 13.19 The G's required for an aircraft to maintain altitude in a coordinated turn are determined by ____________. For propeller aircraft - Maximum angle of climb occurs at the Vfor which maximum excess thrust occurs Maximum climb angle (which is used to clear obstacles on takeoff) occurs at a velocity < V min TR Rate of Climb R/C For a given altitude - For any type of airplane, excess power determines R/C - Induced drag changes P R P C P - = W R . 12.23 An aircraft in which of the following situations is most likely to create the most intense wake turbulence? Interesting airplane; looks like Vy is more than double Vx! One way to resolve this issue is to write our equations in terms of ratios of thrust at altitude divided by thrust at sea level and weight at altitude divided by weight at takeoff. 2.24 Calculate the density altitude for an aircraft at an airport with a pressure altitude of 5,000 feet when the current temperature is 13 degrees C. 2.25 Using Table 2.1, calculate the dynamic pressure, q, at 8,000 feet density altitude and 250 knots TAS. Continue searching. 13.6 (Reference Figure 5.4) What will happen to an aircraft that is flown to the left of the curved lines on the left side of the flight envelope? Once you know the data point where the climb angle is maximized, you can find the actual climb angle with a bit of trigonometry involving the right triangle comprised of the airspeed, horizontal speed, and vertical speed vectors. 1.18 An aircraft's turbojet engine produces 10,000 lbs of thrust at 200 knots true airspeed. This isnt really much different from designing any other product that is capable of more than one task. Find the Groundspeed. The question with the design of an airplane as with a car or a tire, is how do we arrive at the best compromise that will result in a good all around design while still being better than average in one or two desired areas? It should be recalled that CLg is the value of lift coefficient during the ground roll, not at takeoff, and its value is /2k for the theoretically minimum ground run. The other parameter, W/S, or wing loading, is also generally low for sailplanes and high for fighters. Naturally, for this calculation you'll need to use the same units for both values-- a conversion may be necessary. The Role of Performance in Aircraft Design: Constraint Analysis, 9.6 Other Design Objectives Including Take-off, https://archive.org/details/hw-9_20210805, source@https://pressbooks.lib.vt.edu/aerodynamics, status page at https://status.libretexts.org. 1.21 Newton's Second Law of Motion states that: If a body is acted on by an unbalanced force, the body will accelerate in the direction of the force and the acceleration will be directly proportional to the force and inversely proportional to the mass of the body. 3.7 The Center of Pressure __________ move with a change in AOA for a symmetrical airfoil, while it ____________ move with a change in AOA for a cambered airfoil. 6.1 An example of a thrust-producing, fixed wing, aircraft is a, 6.2 An example of a power-producing, fixed-wing, aircraft is a, 6.4 The Q in Ta=Q(V2V1)is the mass flow (slugs/sec). 11.1, what is the minimum landing distance required (50 ft obstacle on final approach) for the given aircraft with the following conditions: 30C OAT, PA 2000 ft, weight 2800 lb., 5-kt tailwind? And it has kinetic energy, which is what kind of pressure? It allows the aircraft to reach takeoff velocity at a lower groundspeed than for a no-wind condition. that can be used in the constraint analysis equations above. 12.22 According to the textbook, one study showed that 0.1 in. 8.11 A propeller which has only one pitch setting is known as: 8.12 A propeller where the pilot can adjust the pitch setting in the air. While you are at it, just the sake of curiosity you might want to also calculate the arctangent of (vertical speed / airspeed) for the same data point. The groundspeed must be increased over the no-wind groundspeed by the amount of the tailwind. 1. Find the distance in nautical miles that it has flown through the air. 5.3 An aircraft will enter ground effect at approximately what altitude? 13.21 As the weight of an aircraft decreases, the VA. 13.22 ______________ of the total lift is the centripetal force that causes radial acceleration. The question is; is there some way to analyze all of these at the same time and come to a decision about optimum or reasonable compromise values of weight, wing area, and engine thrust without having to go through iteration after iteration? It also gives a better ride to the airplane passengers. 7.12 (Reference Figure 7.2) Using Figure 7.2, find the velocity for best range for the airplane at 8,000 lbs. It is called: AERO 1020 Final Review: All Past Test Q's/A's, Materials Science and Engineering: An Introduction, CT Basics 2.0 | Module 1: CT Fundamentals Test, MKT201 700 FULL CHAP-Key 700 Trung sa. 1.17 An airplane weighs 8,000 lbs and is flying at 6,000 ft altitude and an airspeed of 200 fps. 8.23 For a power producer, unaccelerated maximum velocity will occur at the intersection of the full power-available curve and the ________________. If, for example, we went all out to create a plane that could takeoff in a very short distance and then look at its performance in straight and level cruise we would probably find that it isnt very good. 6.20 Where is (L/D)max located on a Tr curve? What altitude gives the best endurance for the C-182? On the other hand, the climb curve should be plotted for optimum conditions; i.e., maximum rate of climb (minimum power required conditions for a prop aircraft) since that is the design target in climb. 10.25 A common source for runway surface and slope information for a particular airport runway is the ______________. 3.25 the rudder controls movement around the ________________ axis range speed to climb than to fly and! * propeller efficiency divided by All up Mass in lbs you 'll need to use same...
